Had this on my k6 750 when I bought it and replacing it with a Leo vince system this week.
From what I understand a lad made a run of them some time back so they are not branded. Good quality, stainless steel system that replaces heavy cat.
I also bought a custom baffle (not the one pictured) for Â£50 which will come with the system. Noise wise its not as loud as it looks. 103 db no baffle, 102 db with baffle without cage and 100 with baffle and cage fitted.
Looking for Â£100 including postage before on buck it on e-bay.
